  • Publication number: 20120329360
    Abstract: A mechanism allowing the control of multiple orbiting bodies comprising: a bearing surface (306) which may or may not be integral to a handle (300); a rotatable section (308) free to move through 360 degrees upon the bearing; and, attached to the rotatable section, an array of two or more pendulums (314, 316) which are first whirled in coplanar orbits and subsequently, via changes made to the attitude of the axis of the rotatable section, in precessing, non-coplanar, non-chaotic orbits equaling the pendulums in number. The pendulums may be identical or have differing properties of length, weight, or aerodynamics affecting their relative tendencies to precess and may be decorated and incorporate elements which emit light and/or sound. In certain applications some or all of these characteristics of length, weight, and aerodynamics, as well as the visual and auditory components are customizable.

  • Publication number: 20120171921
    Abstract: A child's activity toy comprises a plurality of dispensers which will dispense circular discs onto a flat magnetic surface. The circular discs are of different colours, each colour having its own respective diameter, with the colour being applied to each side of the discs. Each dispenser is specific to its own colour, and is biased to its closed, non-dispensing condition. Pressing the dispensing end of a dispenser against the flat magnetic surface will dispense a circular disc; and moving the dispenser while it is pressed against the flat magnetic surface will dispense a series of circular discs. A frame is provided for the flat magnetic surface, and includes a graduated sorter so as to separate the discs of one colour from the discs of any other colour. The respective dispenser for each colour can be filled with the discs from the respective sorter chamber.

    Abstract: A weighted object is attached to a tether and the tether is twisted to cause the weighted object to spin and to change in vertical position. The apparatus which causes the tether to twist can also orbit through a path to cause horizontal motion of the weighted object thereby providing three-dimensional movement to the weighted object. Movable objects are provided as targets for the weighted object with points being given for producing interaction between the weighted object and the movable objects. Also, due to the resonance properties of the tether, many different sculptural forms within the harmonies can be created. By stroboscopically illuminating the tether, further visual forms can be observed. By pulsating the lights on the weight many visual effects can be produced along with altering the tether to produce special effects for film.

    Abstract: A graphic arts toy including a string retaining sketch pad, an elongated string, and means for storing, dispensing and retracting the string. The string retaining sketch pad comprises a flexible, plate-like element having a plurality of upwardly extending, flexible fingers on its top. The fingers are arrayed in equally spaced, parallel, transverse rows. The means for storing, dispensing and retracting the string comprises a string storage, dispensing and retracting pencil having a housing, a string storage dispensing and retracting reel rotatably mounted in the housing, and a string dispensing and retracting tube with one of its ends in the housing and the other of its ends exterior to the housing. When the tube is moved between a pair of fingers, the fingers are flexed apart and the string dispensed there between. The fingers return to their normal position to grip and hold the string after the tube moves to the next pair of fingers.
